The Service List Registry is a federated online directory of audiovisual services, based on open standards. Registered regulators, producers, distributors, and service providers can manage lists of offerings available online and through traditional broadcast networks. This allows compatible devices and applications with different capabilities to discover and access relevant services from multiple sources, offering users choice, convenience and control, on any screen.


Simple Service Selection on any screen


Our purpose is to make it easy for people to find and use media services over any network, on any screen.


  • Open — We use open standards that are freely available to all participants.
  • Equitable — We are fair, reasonable and non-discriminatory.
  • Accessible — Our services are accessible to anyone.
  • Available — Our platform provides the highest level of availability.
  • Transparent — We operate with clarity and integrity at all times.
